128GB DDR5 ECC RDIMM kit for ASUS K14PA-U12

This 128GB kit contains four 32GB DDR5 4800 registered DIMMs built for the ASUS K14PA-U12 server motherboard. It targets administrators expanding memory on AMD EPYC 9004 platforms that require registered ECC modules. The 1Rx4 organisation and 1.1V operation match the board's qualified memory list.

Registered ECC with CL40 timing

Registered buffering and on-die ECC protect data integrity across all 128GB under sustained server workloads. CAS latency of 40 at DDR5 4800 (PC5-38400) delivers the rated throughput without overclocking. The modules ship without heat spreaders, relying on chassis airflow for thermal management.

Four-slot population for 128 core systems

Populating all four slots provides 128GB total capacity with 1Rx4 rank density per module. This configuration suits virtualisation hosts and database nodes running within the motherboard's supported memory map. Builds needing more than 128GB or different rank structures must consult the platform's qualified vendor list.

Questions about this item

Will the 288-pin DDR5 RDIMM modules ever need replacement or maintenance?

The modules are solid-state with no moving parts and include on-die ECC for error correction, so they require no scheduled maintenance or component replacement under normal server operation.

What limit appears first when the 1Rx4 registered DIMMs run at 4800 MT/s continuously?

The primary limit is the JEDEC-defined 1.10 V operating voltage; sustained loads stay within this envelope, so thermal throttling or voltage droop would surface before any frequency ceiling.

How much heat and noise do the four 32 GB sticks produce in a 128-core EPYC 9004 system running all day?

With no heat spreaders and a low 1.10 V supply, the kit adds minimal thermal load and zero acoustic noise, relying on the server's existing airflow for cooling.
